With transient-mark-mode, you can do

        C-SPC ...move... M-;

With the code I sent, people who don't have transient-mark-mode turned on
can still use the comment-region behavior of M-; by doing:

        M-x mark-and-highlight RET ...move... M-;
or
        C-SPC ...move... M-x activate-and-highlight-region RET M-;

This could also be used with other functions who operate on the
region only when transient-mark-mode is turned ON.

Both mark-and-highlight and activate-and-highlight-region are useful and
they should both be provided.  The question is mostly where to bind those
two commands.  I wish mark-and-highlight could be bound to something
similar to C-u SPC and I think that activate-and-highlight-region could
be bound to C-u C-x C-x.
